We report two SFO cases managed at a single centre using VSP, customized cutting guides, and titanium PSIs. Case 1 was a 19-year-old male with maxillary hypoplasia and mandibular hyperplasia treated by Le Fort I osteotomy, vertical ramus osteotomy, and genioplasty. Case 2 was a 30-year-old female with facial asymmetry from unilateral mandibular hyperplasia treated by Le Fort I osteotomy, bilateral sagittal split osteotomy, and mandibular contouring. Both achieved satisfactory functional, occlusal, and aesthetic outcomes at six months without major complications. Maxillary PSI fixation supported predictable plan transfer in both cases, whereas mandibular management still required case-specific strategies. We discuss this pattern in light of current literature.<\/jats:p>","DOI":"10.1093\/jscr\/rjag793","type":"journal-article","created":{"date-parts":[[2026,8,19]],"date-time":"2026-08-19T11:46:05Z","timestamp":1787139965000},"source":"Crossref","is-referenced-by-count":0,"title":["Patient-specific implants and virtual surgical planning in surgery-first orthognathic surgery: a case series and review of literature"],"prefix":"10.1093","volume":"2026","author":[{"given":"Nissia","family":"Ananda","sequence":"first","affiliation":[{"name":"Department of Oral and Maxillofacial Clinical Sciences, Faculty of Dentistry, Universiti Malaya , Kuala Lumpur, 50603 ,","place":["Malaysia"]},{"name":"Dental Department, Universitas Indonesia Hospital, Universitas Indonesia , Jl.
